In October 2011, IBM added native replication of backup data in Tivoli Storage Manager Extended Edition v6.3 to help customers add "warm standby" disaster recovery capabilities to their unified recovery management platform. This is a powerful new feature that can help reduce the costs of maintaining a separate DR point solution, and simplifies the overall management of the environment.

However, when moving data between physical locations, especially over the long distances desired for a true disaster recovery solution, network latency can become a significant issue. TSM replication is extremely efficient, in that it sends only incremental, deduplicated data between sites. But transfer times can still be impacted by network latency over long distances.

To overcome this problem and provide near native transmission speeds, WAN acceleration solutions such as Netex HyperIP can be deployed.

Netex recently completed testing of their solution with the new TSM replication feature and found that it can accelerate data transfer by as much as 6 times, or 12 times with HyperIP’s block-level compression. To learn more, please visit http://www.netex.com/blog/?p=206
